Which makes more sense?
Buy a(a few) terabyte drive(s) a year and cross your fingers?
OR
Write to permanent, verified non-magnetic media which you can put safely in a binder or on racks in hard cases?
(This seems rather obvious to me...)
Just because someone at Apple says it, doesn't make it reality or the best usage scenario in my opinion. Just because there are sheeple customers with very limited needs, or who are too simple to realize they're being duped or having their needs and desires shaped by a company (with monetary motivations), which is in bed with Hollywood and has a vested interest in leveraging DRM crippled products via their 'secure' ecosystem to a bunch of locked in users, doesn't mean the thinking world is going to adopt the idea.
I, for one, value freedom of choice, like the ability to record things (or series) I pay for on cable and the freedom to watch them when and where I want (in full glorious HD)...and guess what, without needing an always on internet, cable or wireless connection (and without needing ever increasing terabytes of fallible magnetic disk based storage).
I also value the ability to back 25GB (of data/music/movies/whatever) at a time off to blu-ray media for archiving, for a mere $1 a disk or 2 with a duplicate. Contrary to the naysayers, unless the current generation of Blu-ray writable media proves to be abysmally poor in the long term I expect that making 2 verified copies will more than suffice for 10+ years of careful storage, unlike any magnetic media I have ever owned or relied on.
What Schiller says may be fine for the neophytes using iTunes on an iMac/tablet crowd, but for any photographers, graphic artists, content creators or anyone who routinely deals with large files they created or own, and has the need or desire to save them, preserve backup copies before making changes etc, this idea is not going to float...
As far as business goes (just pick from a whole host of industries), from graphic artists, to video editors, architects, or engineers, banks, data processors and record keepers...buying enough disk or memory based storage to archive terabytes of data for long term is not practical, and if you work in IT and have had computers for any length of time and do anything with your systems, you will also run into the same issues.
Lack of truly viable long term storage will only work in a marketplace the where convenience of the 'leasing model' and slick polished toys dominate the need to keep and 'own things' or preserve valuable work product.
